Michigan City, Ind., assignor to Sullivan Machinery Company,

`a corporation application April 27l l Claims. (Cl. 230-58) sor outt of an extremely low, compact design especially adapted to use in low vein coal mines or other restricted locations. A further object is eral arrangement of parts. These and other ob jects and advantages of the invention will, however, hereinafter more fully appear.

In the accompanying drawings, there is shown, for purposes of illustration, one form which the invention may assume in practice.

In these drawings- Fig. l is a plan View of the illustrative form of the improved portable compressor outt.

Fig. 2 is a side elevational View of the compressor outt shown in Fig. 1.

Fig. 3 is a view in longitudinal section, taken substantially on line 3-3 of Fig. 1.

Fig. 4 is a cross sectional View With parts shown in end elevation, taken substantially on line 4-4 of Fig. 1.

In this illustrative embodiment of the invention there is shown a portable mine car compressor outt of the low vein type generally comprising a portable base l, supporting a driving motor 2, an air compressor 3 and an air receiver 4, and having a novel cooling arrangement, generally designated 5.

The portable base l is in the form of a truck frame 6 of open-center, rectangular form, havneath the elements supported by the truck frame and in turn supporting bearings at their projecting extremities for journaling car wheels 8 and mounted in suitable axle boxes 9 secured to Supported at the sides of the motor 2. This motor is herein preferably of the electric type, having its power shaft Il! horizontally and longitudinally disposed in the manner shown in Fig. 3. lThe bottom portion of the casing of the motor is transversely recessed at ll to receive the vWheel axle underlying the motor.

its crank oase I2 directly atthe compressor is solely supported by the motor. The compressor 3 is of the V-type, and its cylinders i3 project radially from the axial relation therewith, and extending from the the comside of the latter. parts are mounted on rubber to reduce and protect them from jars.

4The air compressor 3 is of the air-cooled type, provided with the usual cooling iin proved air-cooling system for the compressor is vibration The means for acthe shell, the o'wvopeni'ngs l1 past the compressor cylinders, cooling the latter, vand the air flowing past the the air receiver and laterally through the o pen ings I8 past the exterior of the air receiver, to

cool the latter.

The air compressor conduits 20, 20 each form of air cleaner within the cylinders is discharged out through discharge conduits 23, 23 to the air receiver 4, the conduits 23, 23 having usual heat-radiating fins and extending longitudinally near certain of the air discharge openings I8 in the flow-directing shell I6, so that some cooling effect of these discharge conduits is obtained.

As above mentioned, the truck wheel axles pass across the truck frame beneath the motor and air-directing shell, through transverse recesses above the bottoms of the and the motor and air receiver are supported in a low Aunderslung position on the truck frame,` so that minimum overall height is obtained. It will be evident that by the coaxial arrangement of the motor, air receiver and air-flow-directing shell, a straight-line top surface is obtained, while at the same time cooling is improved and longitudinal compactness made possible. Further, by the particular arrangement of the various elements on the base, the entire outfit is made extremely compact, not only vertically but also longitudinally and laterally, thereby enabling the outfit to operate in low vein mines having entries and stalls of relatively restricted dimensions. Further, by mounting the compressor directly on the motor casing and arranging the other related parts in the manner disclosed, the outt is made not only relatively simple in design but also extremely rugged, well adapted to meet the severe conditions of service. It will also be evident that by forming the compressor crankshaft as an integral continuation oi the motor power shaft, simplicity in structure is made possible, while eiliciency is at the same time improved. These and other advantages of the improved compressor design will be obvious to those skilled in the art.

This application is a continuation of my application Serial No. 37,864, led August 26, 1935.
